The research found that certain chemicals in both mothers and fathers were linked to earlier puberty, with stronger effects seen in granddaughters.
A new study analyzed 53 popular films and found that most depict idealized and aspirational views of puberty, romance, and relationships. This can lead to a disconnect between on-screen representations and real-life experiences, influencing how teens perceive themselves and their place in the world.
Gonadotroph cells controlling puberty and reproduction originate from two separate populations, with the majority produced after birth. This finding could aid in understanding and treating disorders impacting puberty and fertility.

The study suggests that developmental changes driven by the hormonal surge in puberty may override the benefits of female sex hormones later in life.
A study of 793 girls found significant variation in height growth after their first period, with most not reaching the expected 6-8 cm. Early onset of menstruation is linked to greater growth, while late onset is associated with shorter final height. Childhood BMI also plays a role in determining menarche age and subsequent growth.

The researchers also found that three months of calorie restriction has a similar effect, suggesting new potential treatments for kidney diseases.
A new study reveals that boys who smoke in their early teens may damage the genes of their future children, leading to increased risks of developing asthma, obesity, and low lung function. Researchers investigated epigenetic profiles of 875 people aged 7-50 and found changes associated with fathers' teenage smoking.
A new study found an increase in precocious puberty diagnoses among girls during the COVID-19 pandemic due to poor lifestyle changes. Girls with higher body mass index scores were more likely to be diagnosed with early puberty, suggesting a link between rapid weight gain and advanced pubertal development.
The age of individuals with gender dysphoria has decreased, especially among those assigned female at birth, according to research published in General Psychiatry. The estimated prevalence of gender dysphoria rose significantly between 2017 and 2021, while the average age of diagnosis fell from 31 to 26.
